Frequently Asked Questions
Q: What is the difference between 70D and 95A Shore hardness?
A: 70D and 95A are different hardness scales. GWK-MLX55-LW uses 70D Shore hardness, which indicates a durable, load-bearing compound. 95A is on the Shore A scale used for softer materials. The specific 70D hardness in GWK-MLX55-LW is optimized for Mobile MLX55 load wheel performance. Do not confuse these scales. Always verify the exact hardness specification for your jack model.
Q: Are the wheels and bearings sealed against moisture and dust?
A: GWK-MLX55-LW includes precision ball bearings with seals to protect against water and debris ingress. The black ultra-polyurethane wheels resist moisture absorption. However, seals are not perfect and will degrade over time if exposed to harsh conditions. Rinse wheels with fresh water if used near salt, chemicals, or wet environments. Store the jack indoors when not in use.
Q: Can GWK-MLX55-LW wheels be used in outdoor environments?
A: GWK-MLX55-LW wheels are suitable for occasional outdoor use on covered loading docks or warehouses. Prolonged outdoor exposure to UV light, salt air, or direct rain will degrade the polyurethane and cause bearing corrosion. If your operation requires outdoor use, apply a protective cover or store the jack indoors. Inspect wheels and bearings quarterly for damage.
Q: Does GWK-MLX55-LW installation require any modifications to the jack frame?
A: No. GWK-MLX55-LW is designed as a direct bolt-on replacement. The alloy steel axle and complete hardware fit into existing MLX55 frame mounting points without modification. Installation is straightforward: remove the fasteners holding the old wheels, slide them out, insert the new GWK-MLX55-LW assemblies, and secure fasteners. No drilling, welding, or frame alteration is needed.
Q: What symptoms indicate that GWK-MLX55-LW wheels need replacement?
A: Replace wheels when you observe grinding or squealing noise, visible flat spots or chunks missing from the tread, difficulty steering or pushing the jack, or tread wear less than 3mm thick. You can also measure wheel diameter with calipers. If diameter is noticeably smaller than new wheels (indicating severe wear), replacement is needed. Worn wheels increase accident risk.
Q: Is periodic maintenance required after installing GWK-MLX55-LW?
A: No special maintenance is required. Sealed bearings are lubricated and do not need re-greasing. Simply inspect wheels monthly for visible damage and clean debris from wheel treads quarterly. Do not pressure wash wheels as high pressure can damage seals. Under normal warehouse use, GWK-MLX55-LW wheels should provide 24 to 36 months of service life before replacement.
